The 1761 transit of Venus observed from Havana

Record summary

The 1761 transit of Venus prompted international observing campaigns, including efforts in the Caribbean and Spanish imperial world. Havana is a valuable lead for locating an early instrumented observation involving telescopes, timing, and longitude-related coordination rather than an ordinary naked-eye sighting. It may matter for UAP research because it documents how observers handled fleeting, low-contrast phenomena and instrument limitations. The exact observer, apparatus, and surviving report should be verified in expedition accounts or astronomical correspondence; some Havana attributions may derive from campaign summaries rather than local originals.
